And ZDR is still data sharing with a third party. This is the essence of an enterprise agreement, it's not allowed, even if they pinkie promise not to store it.
If your customers allow you to share their data with third parties, then ZDR may be an option for you. I am not a laywer.
Where I see ZDR as being more relevant is in protecting your employer's IP - not allowing a missed setting to mean AI labs can train, retain, and publish/resell your work. It's what we'll consider when the subsidies stop being available - open-router, ZDR - but for coding - not for customer data. Very important distinction.
